GEORGE G. HUNT, or BRISTOL, ILLINOIS.

HARVESTER.

SPECIFICATION forming part of Letters Patent No. 281,368, dated July 17, 1883.

Application filed February 11, 1882. (No model.)

To all whom it may concern Be it known that I, GEO. G. HUNT, of Bristol, Kendall county, Illinois, have invented a new and useful Improvement in Harvesters, the object of which is to obtain a more easily operated and better means by which the platform may be raised or lowered than has heretofore been used.

In the drawings accompanying and forming a part of this specification, and in which similar letters of reference indicate like parts in the several figures, Figure 1 is a back view of what is technically called the grain-wheel standard? of a harvester. Fig. 2 is a crosssection of the same on the line 00 y. Fig. 3 is a view of the back side of a hexagonal washer,

and Fig. 4 is a front view of the same.

The standard A is an open cast-iron frame, having slot or opening J in the center. This slot extends nearly the entire length of the casting, and through the slot passes a bolt, G, which is provided with a square head, which fits into a cavity in a spur-pinion, B. The bolt and pinion may be in one piece, if desirable, and may be cast with a hole extending through the entire length, and in this hole a loose bolt may be placed having the head in a cavity in the back of the pinion, and the nut at the opposite end, so as to grip the washer E, which constitutes the gist of this invention. On the inner side of the standard A is cast a rack, t, into which the teeth of the spurpinion work. The standard A is provided with slots K K K K, through which bolts pass for adj ustably fastening the casting to the grain or divider plank.

H is the hub of the grain-wheel.

m is a tube or sleeve a little longer than the grain-wheel hub, and fitting loosely in the hub. The bolt 0 passes loosely through the sleeve, and at the extremity of the sleeve a hole is bored through the bolt, into which is tightly fitted a pin, I. A slot, 8, on each side of a a central opening, 12, in a washer, E, fits on the bolt and embraces the pin I. This washer is of a form suitable to be grasped by a wrench, which serves to turn the bolt C and pinion B when desired for adjusting. Awasher, F, is inserted between the sleeve and standard, and through this washer the bolt 0 passes. A nut, D, is screwed on the end of the bolt 0, and this, when tightened, holds the grain wheel and platform in any desired position on the standard by pressure of the grip between the nut D and pinion 13 upon the sleeve m, which forms the journal or bearing of the grain-wheel. As the bolt 0 is turned the pinion follows the teeth of the rack, and as the standard is fast to the platform and the bolt 0 is held in the wheel the platform is raised or lowered by simply turning the bolt, as described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a device for adjusting harvester grainwheels, the combination of the standard A, having the slotted side flange for adjustable attachment to the grain-plank, and having a longitudinal slot, J, and an internal rack, with the shaft or journal Gfor the grain-wheel, the pinion on the end of said shaft, and the described clamping device.

2. Combined with the standard A, having the straight central slot, J, and the rack, the shaft 0 and the pinion B, the sleeve m, the hub H, the clamping-nut E, having the grooves or notches s, locking-pin I, and the lockingnut D on the. outer end of the said shaft 0, all substantially as described.
